IMPROVEMENT lN GRAIN-BINDERS.

Specification forming part of Letters Patent No. 188,162, dated March 6,1877; application filed June 5, 1876.

To all whom it may concern:

Be it known that I, DANIEL MOPHERSON, of Caledonia, Livingston county,State of New York, have invented new and useful Improvements in Grain-Binders for Harvesters, of which the following is a full description,reference being had to the accompanying drawings, in which- Figure l isan end elevation; Fig. 2, a side elevation; Fig. 3, an enlarged detail,looking in the directionof the arrow in Fig. 1; Fig. 4, a top view(enlarged) of the holding devices; Fig. 5, an enlarged detail of theeccentric cam; Fig. 6, a section at 1 of Fig. 1, showing the tiltingframe and devices for operating it; Fig. 7, an enlarged end view of thedevices shown; Fig. 8, a detail.

The object of this invention is to improve the construction of automaticgrain-binders to be used in connection with harvesters, and it may bepermanently attached to the machine, or it may be made as a separateattachment. Its nature consists in the use of a single cam attached tothe twister-post to move the same back and forth; in a lever so arrangedas to drive the wire arm or shaft up close to the twister, so that thebinding-wire will be caught by the twister; in, the use of cam and leverfor operating a slide with which a device is connected for grasping thebindingwire; in the use of a second cam connected to the first, andcombined with a lever and a device arranged to hold an endless strap,and at the same time force the binding-wire into the twister; in the useof a third cam connected to the others, and combined with a lever andsliding pinchers, for the purpose of grasping an endless strap andholding it until the bundle is bound; in the use of devices foroperating the endless strap or compressor.

The frame-work A is made in any suitable manner to be applied to aharvesting-machine which has an elevator, B B, and a grain-carrier,which may be made in any of the usual forms, and are, therefore, notfurther described.

The main or driving wheel (not shown) is located, as usual, on the shaftor axle D, which has itsjournal-bearings in the brackets or supports AA. This shaft Dalso passes through the journal-support F on the tiltingcrossbar 0.

On this shaft I), and near the journal-sup port F, is located amiter-wheel, E, which engages with another miter-wheel, F, and drivesthe shaft G, and rotates the cog-wheel V and spur-wheel H, which arepermanently secured thereto.

The construction and operation of the spurwbeel H, pinion I, with plateJ thereon, pitman K, cranks J and L, swinging support 0, collar M, andneedle P, are similar to that of such parts shown and described in my application filed February 3, 1876, except that the needle P ispermanently secured to the collar M, instead of to the shaft N.

R is a fixed shaft, having its supports in F F, which are secured to thetilting cross-bar 0. Upon this shaft is located the twistingpost S,which post is moved back and forth by means of the crank T and eccentricU, the eccentric being operated from the shaft G, to which it isconnected. To this post S is attached the frame Z, which carries theholding devices and the twister-shaft Z, so that as the post is movedback and forth it will carry with it the other devices.

The top of the twister-shaft Z is to be provided with any twistinghookand cutter which do not require a reverse movement to operate them. Thetwister and cutter are not shown.

The twister'shaft Z is located in suitable hearings, and is operated bymeans of the cogs on the wheel Y engaging with the cogs of the beveledwheel Z at the bottom of the twister-shaft Z.

The wheel Y is located on the shaft R, next to the post S, and rotatesthereon. This wheel is provided with cogs only half the way around, theother half having a flange or projection, .10, which engages with thestop to on the beveled wheel Z, and prevents the rotation of thetwisting devices while a gavel is being formed, and during the descentof the needle.

On the shaft R is also located the collar X, to which collar ispermanently secured the cog-wheel W, which wheel en ages with thecogwheel V on the shaft G, and rotates the collar and the devicesthereto attached. This wheel W also operates the cog-wheel Y. To thiscollar X are permanently attached the three cams aft, so that as thecollar is rotated the cams will operate their several devices.

The cam a engages with the lower end of the lever b, which lever ispivoted near its middle to the frame Z, and operates the sliding bar a,moving it back and forth. To the end of this bar a is pivoted a tooth orjaw, d, which jaw has a rearward extension, d, with which the spring ecomes in contact. As the bar 0 is pushed forward by means of the cam aand lover b, the tooth orjaw at will be closed when the extension atstrikes against the frame Z, and on the return movement of the bar citwill be opened by means of the spring 0, the object of this device beingto grasp and hold the end of the binding-wire after a bundle has beenbound. The cam f engages with the lower end of the lever g, which ispivoted below its center to the frame Z, and operates the bar h, whichbar is located at the top of the lever, and, as shown, is a partthereof. The object of this device is to hold the endless strap whilethe needle-bar is ascending. The cam z engages with the lower-end of thelever j, which is pivoted near its center to the frame Z, and operates asliding bar, In. This bar It slides back and forth in suitable supportslocated on top of the frame Z, and to it ,is attached the spring 0. Tothis bar is pivoted the movable arm or jaw Z, which jaw is closed bymeans of the extension m coming in contact with the plate or projectionn, as the bar It is moved forward, and is opened by means of the spring0 engaging with the rear end thereof as the bar 70 is moved back. Thebar It slides back or in rear of the plate q, and the jaw l closesagainst it. The object of this device is to grasp the endless strapwhile the twisting is being done, and during the time that such strap isreleased from the bar It. The parts are to be so timed that the cam fand lever g will draw back the bar h and release the endless strap rwhen the neodle-bar has nearly completed its descent, at which time thecam t and lever j will cause the bar It to move forward, closing themovable jaw 1, so as to grasp the strap 1" before the bar h releases it.As the needle-bar ascends, the pinchers will be withdrawn, and the bar hadvanced to hold the strap. By this arrangeinent the endless strap willbe held, either by the bar h or jaw 1, during both the ascent anddescent of the needle. The cam a is to be so timed that it will advancethe bar a and release the binding-wire when the twisting commences, andalmost immediately return and grasp it again, and hold it during theascent of the needle, so that it will be ready to be carried around thenext bundle by the descent of the needle. The wheel V is provided with apin, 6, which comes in contact with the lever c, and drives it forwardtoward the binding devices. To the lower end of this lever c is attacheda spring, f, by means of which the lever is returned. The upper end ofthe lever 0 comes in contact with the end of the needle, and the objectof the device is to force the needle up to the twister, so that thebinding-wire will be caught thereby. The bar 0, as shown, is pivoted, bymeans of the support F, to the axle D of the main or driving wheel. Thisbar G is provided with a pin, a, which engages with the slot 12 of thesliding bar D, which bar D is operated by means of the lever E. (SeeFig. 6.) By this means the bar 0 can be tilted so as to bring thebinding devices, which are attached thereto, in such a position as tobind the gavel near its center.

It is desirable to compress the bundle into shape by means other thanthe binding-wire, in order to save any undue strain upon the wire. ThisI accomplish as follows: To the end of the shaftN is permanentlyattached an arm, Q. On the end arm is located a roller, s, and attachedto this arm is a support, h i. To the upper end of h is pivoted a rod,j, in the, end of which is a roller, 70. To the rear end of the rod j.and i is secured a spring, Z. The end of the needle P is also providedwith a roller, u. Over these rollers u, s, and h, and around the collarM, the endless strap 1 passes, as shown in Figs. 1 and 7. The endlessstrap 1' being held at one point by the bar h, as before described, asthe neodle bar descends it will carry the strap around the bundle orgavel and compress it into shape. The plate g on the frame Z, over whichthe strap 1" passes, should be rounded, so as not to unnecessarily wearthe strap at that point. The spring t permits the compressing-strap r topass around the bundle, and it also serves the office of a take-up whenthe bundle is released.

The take-up section h, t, j,k, and I may be omitted, as the endlessstrap will operate well without it, for the bundle or sheaf will act asa sufficient take-up.

The receiverO is made in two parts, as usual, and is supported upon thetilting cross-bar G by means of suitable standards or posts G.

In operation, out grain is received upon the receiver (3, the partsbeing in the position shown in Fig. 7, in which position thehinding-wire will pass from the spool (not shown) down through the eye02 of the needle P; thence through the hole 1) of the plate 1;,- thencedown to the holding device 0 d, where its end is held. At the same timethe bar h will hold the compressor-strap 1'. As the machine advances thebent arm 0 will be carried forward by means of the wheel I, pinion J,and pitman L, and the needle-arm P will be carried down through theaccumulated grain.

The operation of the compressor is as follows: The endless strap a" islocked below by the gripers k l, and is held above between the roller 8and plate g of the arm or support Q by pressure from the spring 9,regulated by the screw t, to give the gavel the required pressure orcompression. As the arm P descends the strap is carried around thegavel, bringing into shape and compressingit. The arm P brings the straparound against or to the frame or head Z, at which time the arm or bar his advanced so as to catch and hold it at that point. The strap remainsin this position until the twisting is completed, when the arm or bar Itis withdrawn, releasing the lock, leaving the rear of that portion ofthe strap used in compressing free, so that the bundle falls out, or isfree to fall out behind. The bar 70 is advanced as soon as the bundle isreleased, and locks the strap again close to the bar h, when theoperation is ready to be repeated. By this operation the band or strap 1is made to travel around or revolve by steps, an advance section thereofbeing used as the bundles follow each other, and by thus looking andreleasing the compressor-band from below, or at the twister, it is freedfrom the bound bundles, so as not to interfere with their discharge, andI am enabled to use a strong compression. The amount of the compressionis regulated by the set-screw 1., so that heavy or light compression maybe had, as desired.

When the needle has descended to its lowest point, the pin 6 will causethe lever c to move forward and force the needle a little fartherforward, so as to bring the binding- Wire within reach of the twister.The twister is then operated by means of the wheel Y, at which time thebinding-wire is released from c d and grasped again, as beforedescribed. Then the wire will be twisted and cut, and the bent arm 0carried back. As the needle ascends the parts are returned to theposition shown in Fig. 7, ready for the next bundle, when the sameoperation is repeated.

At the same time that the bent arm 0, and the parts thereto attached,are advanced, the post S, and the twisting and holding devices connectedtherewith, will be advanced by means of the crank T and eccentric U, andwhen the bent arm 0 is returned the post S and the other devices, willalso be returned.

What I claim as new, and desire to secure by Letters Patent, is asfollows:

1. The eccentric U and crank T, in combination with the shaft G andtwister-post-S, sub stantially as and for the purposes specified.

2. The shaft R, collar X, cam a, and lever b, in combination with thesliding bar 0 and movable jaw d, frame Z, and spring 1, substantially asand for the purpose set forth.

3. The combination of the shaft R, collar X, camsf i, levers g and j,with the bars h and k, for holding and locking the strap 1',substantially as specified.

4. The endless strap 7', in combination with the support Q, needle-armP, and two alternately holding and releasing bars located at or near thetwister for compressing gavels and releasing bundles, substantially asspecified.

5. The roller 8 of the support Q, plates g 9, spring 9, and set-screw t,in combination with the endless belt 1", for adjusting the tension,substantially as set forth.

6. The endless strap 1', in combination with the support Q and roller 8,needle-bar P, and roller u, rod or bar j, roller 70, and spring 1, andholding devices h and k l, substantially as described.

7. The lever or pivoted bar 0, in combination with the wheel V and pine, for forcing the needle-arm up to or against the twister,substantially as specified.

8. The tilting bar 0, having a pin, a, in combination with the slidingbar D, provided with a slot, b, and lover E, substantially as described.
